You need to do the following:

• Download a fresh copy of WordPress to your desktop and unzip.
• Open the wp-config.php file in a text editor and edit the database name, username and password to the same database name, username and password to what you have in your hosting.
• If you do not know the database password you can generate a new password in yoru hosting. Leave the database user the same.
• Google ‘WordPress salts’ and you will geta page that gives you some random salt strings. Update these in the config file too.
• Upload the only the config file to your WordPress install this will kick your website back in to action.
• Do not upload a fresh copy of WordPres. Do not upload a fresh wp-content folder – both of these could wipe your website.
